FIELD OF THE DISCLOSURE

The present disclosure relates to a transmission and an agricultural orindustrial commercial vehicle including a transmission.

BACKGROUND

Different types of transmissions are used in agricultural or industrialcommercial vehicles. A usual powertrain architecture provides a tractionmotor or engine and a transmission. Torque from the traction motor canbe transmitted to the ground engagement means by the transmission.

SUMMARY

A multiplicity of different transmissions, for example infinitelyvariable transmissions (IVT), partial power shift transmissions (PPST)or power shift transmissions (PST) are nowadays used in agricultural orindustrial commercial vehicles, for example agricultural or industrialtowing vehicles, such as tractors or haulers. The transmissions enablethe propulsion of the commercial vehicle to be varied in anuninterrupted manner beyond simply varying the rotating speed of thetraction motor, even at a high towing load caused for example by a workmachine installed thereon, such as a soil cultivation apparatus (forexample a plough) or the like. The transmission of a commercial vehiclehere is generally embedded in a higher-level power train architecture ofthe entire commercial vehicle. A usual power train architecture providesa traction motor or engine and a transmission. These can be disposedalong a vehicle longitudinal axis, thus a longitudinal axis of thecommercial vehicle that is an axis that runs in a longitudinal directionof the commercial vehicle, or along a forward travel direction of thevehicle, for example in a front half of the commercial vehicle. Thecommercial vehicle, for example the traction motor, can comprise acrankshaft which may for example be disposed in the proximity of avehicle central plane or along the latter, for example a verticalvehicle central plane. A force and/or a torque from the traction motorcan be transmitted to the ground engagement means, for example wheelsand/or chains and/or tracks, of the commercial vehicle (propulsion,traction), by the transmission. The transmission, for example a primarytransmission unit, can be disposed along the vehicle longitudinal axisand/or along the vehicle central plane and/or, counter to the forwardtravel direction, behind the traction motor in the direction of the rearend of the vehicle; the primary transmission unit can for example bedisposed directly on the traction motor. The drive element, for examplethe input shaft, of the transmission, for example of the primarytransmission unit, can be connected to and/or be able to be driven bythe crankshaft of the traction motor. The crankshaft axes of thecrankshaft of the traction motor, and the drive element of thetransmission, can be aligned and/or disposed so as to be mutuallycoaxial. Alternatively, the crankshaft axis and the drive element can bemutually offset or disposed at a mutual angle. The first drive elementof the transmission can be connected or be able to be connected directlyor indirectly to the ground engagement means in order for the latter tobe driven. As a result, a force flux and/or torque flux from thetraction motor to the output element and further to a front and/or reardriven axle, and thus to the ground engagement means, can be establishedby way of the crankshaft and the drive element.

It can be a disadvantage that the transmission requires too muchinstallation space in these commercial vehicles with the known powertrain architecture. The many shafts and gear sets which are present inknown power shift transmissions can be a disadvantage. As a result, thetransmission requires installation space which could be utilized foradditional components and/or a cab of the commercial vehicle, forexample. Moreover, the known transmissions can have an insufficientnumber of gears in the operating range, and/or an insufficient speedrange, and/or an insufficient spread between the gears. Especiallymissing can be a sufficient and optimal number of transmission ratios inthe operating range of the speeds in the field. The known transmissionswith many shifting elements, for example clutches and/or brakes and/orshifting collars or synchronizers, respectively, can be complex intechnical and constructive terms and cause high production costs.

The present disclosure is therefore based on the object of proposing atransmission and a commercial vehicle by way of which theafore-mentioned issues are overcome. A transmission and a commercialvehicle by way of which a diversity of transmissions in a commercialvehicle is increased and/or which are less complex in technical and/orconstructive and/or economical terms, and/or wherein the transmission isof a more compact construction mode, and/or the installation space, forexample in the commercial vehicle, such as below a cab and/or betweenthe traction motor and the rear axle module can be better utilized,and/or the output and/or the fitness for purpose of the transmissionand/or of the commercial vehicle is improved, and/or has a sufficientnumber of transmission ratios are to be proposed for example.

This object is achieved by a transmission having the features of one ormore of the following embodiments, and by an agricultural or industrialcommercial vehicle having the features of one or more of the followingembodiments. Further embodiments of the disclosure are apparent from thefollowing.

Proposed according to the disclosure is a transmission for transmittinga torque generated by a traction motor to at least one front and/or reardriven axle of an agricultural or industrial commercial vehicle. Thetransmission comprises a drive element, for example the input shaft, anda first output element, for example a first output shaft, and a primarytransmission unit. The primary transmission unit comprises at least onefirst planetary gear set having a first sun gear, a first ring gear, afirst planet carrier, for example a first web, and a first planet set,and a second planetary gear set having a second sun gear, and a thirdplanetary gear set having a third sun gear and a third planet set. Thesecond planetary gear set and the third planetary gear set have a firstcommon planet set and a first common ring gear and a first common planetcarrier, for example a first common web. The primary transmission unitmoreover comprises at least five, for example exactly five, shiftingelements. The transmission furthermore comprises an intermediate gearboxwhich has at least two, for example exactly two, shifting elements. Theintermediate gearbox can comprise at least one or two planetary gearsets. At least two forward gears can be established by the intermediategearbox. The transmission furthermore comprises a reversing unit,wherein the reversing unit comprises at least two, for example exactlytwo, shifting elements. The reversing unit is for example designed forchanging a rotating direction of the transmission, such as for changinga rotating direction of the first output element, and for example of asecond output element. Moreover, at least one forward gear and onereverse gear can for example be established by the reversing unit. Thereversing unit can comprise at least one planetary gear set, or at leasttwo gear sets having in each case one idler gear and one fixed gear. Atleast two, for example exactly two, of the shifting elements of theprimary transmission unit and at least one, for example exactly oneshifting element or two shifting elements, of the intermediate gearboxand at least one, for example exactly one, shifting element of thereversing unit are activatable, for example selectively activatable,such as lockable and releasable, and/or throwable and/or shiftableand/or selectively engageable, in combinations of at least four, forexample exactly four or five, shifting elements so as to establish atleast twelve, for example exactly twelve or twenty-four, forward gearsbetween the drive element and the first output element and/or the secondoutput element. Additionally, at least twelve, for example exactlytwelve or twenty-four, reverse gears can moreover be established. Insome embodiments, fewer than twelve or twenty-four reverse gears mayalso be actually used.

The first common ring gear can be, for example permanently, connected tothe reversing unit or to the intermediate gearbox, for example connectedin a rotationally fixed and/or drivable manner. The primary transmissionunit can however also comprise a first intermediate element, for examplea first layshaft. Specifically, the first intermediate element can be,for example permanently, connected to the first common ring gear and tothe reversing unit or to the intermediate gearbox, for example connectedin a rotationally fixed and/or drivable manner.

Likewise, the primary transmission unit can at least partially or elsecompletely comprise the drive element and/or the first output element.At least six forward gears between the drive element and the firstcommon ring gear, for example between the drive element and the firstintermediate element, can be established by the primary transmissionunit. At least two forward gears can be established by the intermediategearbox. A total of at least twelve forward gears can thus beestablished by the primary transmission unit and the intermediategearbox. One forward gear and one reverse gear can be established by thereversing unit. A total of at least twelve forward gears and twelvereverse gears can thus be established by the primary transmission unitand the intermediate gearbox and the reversing unit.

The planetary gear sets of the primary transmission unit, when viewedaxially, can be disposed in the following order: first planetary gearset, second planetary gear set, and third planetary gear set. The firstplanetary gear set can be configured as a simple minus planet set. As isknown, a minus planet set comprises a sun gear, a ring gear, and aplanet carrier, planetary gears which mesh in each case with the sungear and the ring gear being rotatably mounted on said planet carrier.As a result, the ring gear has a rotating direction which is counter tothat of the sun gear when the planet carrier is held stationary. Thefirst planet set can for example have a set of first planetary gears.The first planet set can comprise three first planetary gears. The firstplanet set, thus the first planetary gears, can be rotatably mounted onthe first planet carrier. The first planet set can mesh with the firstsun gear and the first ring gear, thus constantly engage so as to meshfor example with said first sun gear and said first ring gear. The thirdplanet set can comprise a set of third planetary gears, for examplethree third planetary gears, and/or the first common planet set cancomprise a set of first common planetary gears, for example three firstcommon planetary gears. The third planet set, thus the third planetarygears, and the first common planet set, thus the first common planetarygears, can be rotatably mounted on the first common planet carrier.Moreover, the third planet set can mesh with the third sun gear and thefirst common planetary gears, thus constantly engage so as to mesh forexample with said third sun gear and said first common planetary gears.Moreover, the first common planet set can mesh with the second sun gearand the first common ring gear and the third planet set, thus constantlyengage so as to mesh for example with said second sun gear and saidfirst common ring gear and said third planet set. In other words, thesecond planetary gear set and the third planetary gear set can beconfigured as a double planetary gear set, for example as a Ravigneauxand/or a Lepelletier planetary gear set. The double planetary gear sethere can comprise the second sun gear and the third sun gear, the thirdplanet set and the first common planet set, the first common planetcarrier and the first common ring gear. The third planet set and thefirst common planet set can be rotatably mounted on the first commonplanet carrier. Three planetary gears are in each case usually used forthe planet sets of the transmission, thus for example the first planetset and the third planet set, and/or the first common planet set and/ora second common planet set, and/or a fourth planet set and/or a fifthplanet set and/or a sixth planet set. However, a different number ofplanetary gears would also be conceivable, for example in each case fouror five or six or a plurality of planetary gears. The number ofplanetary gears here has an influence on the maximum transmissibletorque.

In other words, a multi-stage transmission in a planetary constructionmode, comprising the drive element which can be connected to a tractionmotor, for example in a drivable and/or rotationally fixed manner, isproposed as a transmission. Furthermore, the transmission can compriseat least four, for example five or six or more planetary gear sets, atleast two rotatable shafts, the drive element and the first outputelement as well as at least nine, for example exactly nine or twelve,shifting elements. The shifting elements of the transmission can beembodied as frictional shifting elements and/or multi-disk shiftingelements. The shifting elements can likewise be shifting elementsembodied as form-fitting shifting elements. The shifting elements can bebrakes and/or clutches. The activation, for example the selectiveactivation or engagement, of the at least four, for example exactly fouror five, shifting elements of the transmission can bring about differenttransmission ratios between the drive element and the first outputelement and/or the second output element such that for example at leasttwelve, for example exactly twelve or twenty-four, forward gears, andfor example exactly as many or fewer reverse gears can be established.

The first output element can be provided for driving the rear and/orfront ground engagement means of the commercial vehicle, and/or be ableto be connected to a rear axle module. As a result, a force flux and/ortorque flux between the first output element and the rear and/or frontdriven axle can be established such that a force and/or a torque can betransmitted to the rear and/or front driven axle of the commercialvehicle, for example. The transmission, for example the primarytransmission unit, can comprise the second output element, for example asecond output shaft. The second output element can be provided fordriving the front ground engagement means of the commercial vehicle,and/or be able to be connected, or be connected, in a drivable manner toa front axle module. As a result, a force flux and/or torque fluxbetween the second output element and the front driven axle can beestablished such that a force and/or a torque can be transmitted to thefront driven axle of the commercial vehicle, for example, and a forceflux and/or torque flux between the first drive element and the reardriven axle can for example be simultaneously established. A force fluxand/or torque flux, for example a separate force flux and/or torqueflux, from the first output element to the rear driven axle, and fromthe second output element to the front driven axle, can thus beestablished.

The transmission can have a rear axle module. The rear axle module canat least partially or completely comprise the rear driven axle and/or arear axle differential. The rear axle module, for example the rear axledifferential, can comprise a rear axle pinion, for example a drive bevelgear, or a bevel pinion, and a rear axle gear wheel, for example a bevelgear wheel or a ring gear wheel. The rear axle housing can receive therear axle module, for example the rear axle differential, and/or atleast partially receive the rear driven axle. The first output elementcan be connected to the rear axle pinion, or the rear axle pinion andthe first output element can be configured as an integral component. Thetransmission can have a front axle module. The front axle module canpartially or completely comprise the front driven axle and/or a frontaxle differential. The front axle module, for example the front axledifferential, can comprise a front axle pinion, for example a drivebevel gear, or a bevel pinion, and a front axle gear wheel, for examplea bevel gear wheel or a ring gear wheel. A front axle housing canreceive the front axle module, for example the front axle differential,and/or at least partially receive the front driven axle. The secondoutput element can be connected to the front axle pinion, or the frontaxle pinion and the second output element can be configured as anintegral component.

The transmission can comprise a primary transmission housing whichreceives the primary transmission unit, and/or a reversing unit housingwhich receives the reversing unit, and/or an intermediate gearboxhousing which receives the intermediate gearbox, and/or a rear axlehousing which receives the rear axle module, and/or a front axle housingwhich receives the front axle module. The primary transmission housingand/or the reversing unit housing and/or the intermediate gearboxhousing and/or the rear axle housing and/or the front axle housing,independently of the number of planetary gear sets and/or shafts, canhave a predefinable and/or fixed installation space, thus a predefinableaxial and lateral extent. As a result, the housings, for example in astate installed in the commercial vehicle, always have the sameinstallation space and/or thus a modularity in terms of the installationspace. The primary transmission housing and/or the reversing unithousing and/or the intermediate gearbox housing and/or the rear axlehousing and/or the front axle housing can be configured so as to beintegral or in multiple parts. The primary transmission housing and/orthe reversing unit housing and/or the intermediate gearbox housingand/or the rear axle housing and/or the front axle housing can thereinreceive components of the transmission.

The transmission can moreover comprise a coupling element. The couplingelement can be disposed on the drive element. The traction motor, forexample the crankshaft or a drive shaft of the traction motor, and thecoupling element or the drive element, in a state installed in thecommercial vehicle, can be able to be connected, or be connected, in arotationally fixed and/or drivable manner, for example by way of ashaft-to-hub connection. As a result, a torque flux can be able to beestablished between the primary transmission unit and/or the reversingunit and/or the intermediate gearbox and/or the rear axle module and/orthe front axle module; for example, the drive element and thus the firstoutput element and/or the second output element can be drivable by thetraction motor.

In a state in which the transmission is installed in a commercialvehicle, a transmission longitudinal axis, thus a longitudinal axis ofthe transmission that is an axis that runs in a longitudinal directionof the transmission, can be disposed so as to be parallel to or coaxialwith the vehicle longitudinal axis. The planetary gear sets can bedisposed axially or along the transmission longitudinal axis.

It is relevant to the disclosure that the transmission has sufficienttransmission ratios, and/or the complexity in terms of construction andthe installation size, for example the installation space, or theweight, respectively, are optimized and the degree of efficiencyimproved in terms of losses related to toothing and drag. Minor torquesare present in the shifting elements and in the planetary gear sets ofthe transmission, the wear on the transmission being reduced as aresult. As a result of the embodiment of the transmission and/or as aresult of the minor torques, an embodiment which is simple in terms ofconstruction, for example a compact construction mode, thus a smallervolume of the transmission and/or smaller dimensions are/is likewiseachieved such that the installation space required by the transmissionand the corresponding costs are reduced. Moreover, minor rotating speedsare also present at the shafts, the shifting elements and the planetarygear sets. The transmission is moreover conceived in such a manner thatan adaptability to different power train architectures in the directionof the force flux and/or torque flux, as well as in terms of space, ismade possible. The transmission can be installed in the commercialvehicle in a front-transverse construction mode, or in the context of astandard drive, for example. In an installed state of the transmission,the installation space, for example the axial and radial space, of thetransmission in the commercial vehicle can be minimized by virtue of thespatial disposal of the three planet sets. Moreover, the transmissionhas a minor or minimal number of gear wheels and shifting elements, as aresult of which the transmission, for example also in a state installedin the commercial vehicle, has a more compact construction mode which issimpler in terms of construction, the complexity in terms ofconstruction being significantly reduced. A positive degree ofefficiency in terms of the losses related to toothing and drag isobtained in the forward and/or reverse gears in the transmission. Thetransmission and the commercial vehicle overall are thus less complex intechnical and constructive and economical terms. An additionalinstallation space for components outside the transmission is likewisemade possible. Moreover, the cab can be disposed deeper down, thus so asto be displaced in the direction of a support surface of the commercialvehicle, than cabs in known commercial vehicles. As a result of theembodiment of the transmission according to the disclosure, transmissionratios which are suitable for commercial vehicles and an increasedoverall spread of the multi-stage transmission are obtained, bringingabout as a result an improvement in the driving comfort and asignificant reduction in fuel consumption. The output and/or theroadworthiness and/or road holding of the commercial vehicle can thus beimproved as a result.

In an embodiment of the disclosure, the reversing unit and/or theintermediate gearbox in the direction of the force flux and torque fluxare disposed downstream of the primary transmission unit. Theintermediate gearbox in the direction of the force flux and torque fluxcan be disposed downstream of the primary transmission unit and upstreamof the reversing unit, or the reversing unit in the direction of theforce flux and torque flux can be disposed downstream of the primarytransmission unit and upstream of the intermediate gearbox. The primarytransmission unit and/or the intermediate gearbox and/or the reversingunit can be disposed along the transmission longitudinal axis and/or thevehicle longitudinal axis. Likewise, the intermediate gearbox and/or thereversing unit can also be disposed upstream of the primary transmissionunit. As a result, a compact axial construction mode is achieved.

The above-mentionedadvantages according to the disclosure are achieved by virtue of thecombination of the primary transmission unit and the reversing unit.Moreover, the reversing unit by virtue of the described planetaryconstruction mode has a minor axial construction length. This has anoverall advantageous effect for example on the axial construction lengthof the transmission and/or the installation space of the transmission,for example in a state in which the transmission is installed in thecommercial vehicle.

In some embodiments, the transmission comprises a power take-off module.The rear axle module, for example the rear axle housing, can be disposedbetween the power take-off module and the primary transmission unit.

The power take-off drive shaft, in a state in which thetransmission is installed in the commercial vehicle, can be able to bedriven by the traction motor, for example also be coupled in such amanner that the power take-off drive shaft is drivable by the tractionmotor. The power take-off module, for example the power take-offgearbox, by way of the power take-off drive shaft, for example also byway of the rear axle module, for driving can thus be operativelyconnected to the traction motor by way of the drive element and/or bedrivable by said traction motor by way of the drive element. In thisway, a direct and thus particularly energy-efficient transmission of adrive output from the traction motor to a power take-off module, forexample the power take-off output of the commercial vehicle, ispossible.

In some embodiments, the first output element is connected, or able tobe connected, to the second intermediate element, and the first outputelement is for example able to be drivable by the second intermediateelement. The second intermediate element and the first output elementcan for example be able to be coupled by a gear set. To this end, thefirst output element can be drivable by way of the gear set or by thegear set. The gear set can comprise two permanently meshing outputgears, a first output gear and a second output gear, which can beconfigured as fixed gears. The first output gear can be connected in arotationally fixed manner to the second intermediate element, and thesecond output gear can be connected in a rotationally fixed manner tothe first output element. The second output element can be connected, orable to be connected, to an output clutch, for example be connected orable to be connected in a releasable, rotationally fixed and/or drivablemanner.

DETAILED DESCRIPTION

The embodiments or implementations disclosed in the above drawings andthe following detailed description are not intended to be exhaustive orto limit the present disclosure to these embodiments or implementations.

FIG. 1 shows a schematic illustration of a first exemplary embodiment ofan agricultural or industrial commercial vehicle 10 according to thedisclosure, for example of a tractor or hauler, having a transmission 20according to the disclosure. The fundamental construction of acommercial vehicle 10 is assumed to be known to the person skilled inthe art. The commercial vehicle 10 comprises a cab 12, a front drivenaxle 14, and a rear driven axle 16. The rear driven axle 16 can bepermanently driven, and the front driven axle 14 can be activated ondemand or be permanently driven. The commercial vehicle 10 furthermorecomprises a traction motor 18 which can be embodied as an internalcombustion engine. The transmission 20 has a power train architecturewhich may be assembled from various individual transmission modules, asdescribed hereunder. The power train architecture described here, in theforce flux and torque flux, proceeding from a traction motor 18, canhave a transmission 20 according to the disclosure, having a primarytransmission unit 22 and, for example, a rear axle module 24 and a powertake-off module 26.

The transmission 20 here, for example the primary transmission unit 22,counter to the forward travel direction 300 of the commercial vehicle,is disposed downstream of the traction motor 18 and/or along a vehiclelongitudinal axis 52, thus a longitudinal axis 52 of the commercialvehicle 10. The transmission 20, for example the primary transmissionunit 22, for driving is operatively connected to the traction motor 18,and/or can be drivable by the traction motor 18. The rear axle module 24can be disposed downstream of the transmission 20, for exampledownstream of the primary transmission unit 22 or of a reversing unit120, or of an intermediate gearbox 150. The rear axle module 24 here,for driving can be operatively connected to, and/or be drivable by, theprimary transmission unit 22 or the reversing unit 120 or theintermediate gearbox 150. A force and a torque of the traction motor 18can be transmitted by way of different gear stages to a first outputelement (see FIG. 2 , reference sign 32) and/or a second output element(see FIG. 2 , reference sign 190) by the transmission 20 shown.

The front and/or rear driven axle 14, 16 convert a rotation ofthe first and/or second output element 32, 190 to a rotation of one or aplurality of ground engagement means 28, and thus to a propulsion of thecommercial vehicle. Therefore, the commercial vehicle, as a function ofa gear stage selected in the transmission 20, can be driven at avariable rotating speed. Consequently, a commercial vehicle 10 equippedwith the transmission 20, as a function of the gear stage selected inthe transmission 20, can be moved in different speed ranges.

The towing vehicle 10 can have one or a plurality of ground engagementmeans 28, here illustrated in the form of wheels 40, 42, which engagewith a hard ground 302 so as to transmit traction forces, and/or by wayof which the towing vehicle 10 is supported on the hard ground.
